Application filed December 7, 1916. Serial No. 135,570.

To all tvhom it may concern Be it known that we, HENRY A. ALHEIT and JOHN A. Borxnn, citizens of the United States, and residents of the city of New York, boroiigh of Manhattan, in the county and State of New York, have invented a new and Improved SandingDevice for Vehicles, of which the following is a full, clear, and exact description.

This invention relates to sanding devices for vehicles and has for an bbject an improved oonstruction whereby sand may be discharged at any time upon the traction surface in front of the wheels of any form of vehicle whereby slipping or skidding is retarded or prevented.

Another object in view is to provide a sanding device for motor driven vehicles constructed so that the exhaust may be automatically turned on to the sanding device for forcing sand on the traction surface beneath the wheels of the vehicle at the time, and perhaps before, the brakes have been applied.

A still further object in view is to provide a sanding device for motor driven vehicles in which the exhaust from the motor will discharge the sand, and means for turning on the exhaust in the proper direction will be applied automatically when the brake is being set. I

In the accompanying drawings:

Figure l-is a side view of part of a motor driven vehicle with certain parts broken away, the same being shown in connection with a sanding device embodying the invention.

Fig. 2 is a top plan view of .the structure shown in Fig. 1.

Fig. 3 is an enlarged detail perspective view of an exhaust distributing device em bodying certain features of the invention.

Fig. 4 is a longitudinal vertical. section through a sand distributing well or trap.

Fig. 5 is a detail fragmentary side view on an enlarged scale of means for connecting the brake pedal with the operating rod used in shifting the exhaust, the same disclosing certain features of the invention.

Fig. 6 is a view similar to Fig; 5 but with certain parts shown in section and the remaining parts moved to an operative position.

Referring to the accompanying drawings by numerals, 1 indicates a motor driven vehicle of any desired kind, said vehicle being provided with the usual brake pedal 2 and an exhaust mufiier 3. A fitting 4 (Fig. 3) is provided in the exhaust. pipe between the mufiier 3 and the engine, said fitting having an inlet opening 5 for receiving exhaust from the engine and outlet openings 6 and 7, outlet opening 6 directing the exhaust to the muffler 3 while outlet opening valves and a'link 14. An arm 15 is connected with crank 13,*said arm having a clevis 16 pivotally connected thereto, said clevis having in turn pivotally connected thereto the operating arm 17 and spring 18. One end of spring 18 is connected with the bracket 19 on section 7 whereby the parts are normally held in the position shown in Fig. 3 so that the exhaust will pass into the muffler 3. However, when arm 17 is pulled in the direction of the arrow the exhaust will begin to pass into section 7 the amount of exhaust being in proportion to the movement of the rod 17 and the subsequent movement of the valves 10 and 11.

The rod 17 extends to near the front of the machine or to some convenient point, as shown in Figs. 1, 5,and 6, where it passes through a supporting bracket 20, said bracket having a slot 21 therein. An adjustable stop 22is connected to the rod 17 so as to engage the stop 23 on the rod 24: when the parts are moved to the position shown in Fig. 6, said movement beingassisted by the spring 25' when the cam 26 is moved cent the wheel 31 of the vehicle 1, whereby the operator may at any time move the cam 26 out of the way, namely, to the position shown in Fig. 6. This will cause the rod 17 against accidental movement by a set screw new The rod 2'1- is connected with thcusual brake rod as shown in dotted lines in Fig. 1, whereby whenever the pedal 2 is depressed for applying the brakes the rod 1? will be pulled provided member 30 has been operated for moving iJAB cam 26 to the position shown in Fig. 6. In operating the pedal L there is usually some considerable lost motion before the brake shoe engages the bralre w reel, and this lost motion permits an appreciable movement of rod 11 before the brakes are applied, thus allowing a discharge of the exhaust through section 7 and pipe 8 a short time before the brakes are quickly applied. In fact, by forcing the pedal 2 downwardly somewhat and merely feel the brake as it is termed, sand may be applied, the rod 17 being moved as just described. As soon as the exhaust is turned on to the section i" and pipe 8 it will pass through the trap or well 9 and from thence to the Y-shaped fitting 33 where it is divided and passes through the pipes 3% and 35, respectively, to the discharge nozzles 36 and 37. The nozzles 36 and 87 may be wide or any other shape preferredsoas to produce a proper discharge of the sand against and in front of the wheels of the vehicle.

In order that thesand may bebrought into the path of movement of the enhaust from pipe 8 in comparatively small quantities, the wellor trap 9 is provided with a projection 38 through which'the end of a pipe 89 passes, said pipe being clamped a0. It will be observed that the well or trap 9 has a downwardly extending section 41 in which the clean-out plug %2 is fitted whereby a cup structure is produced for receiving sand through pipe 3%, thus preventing. more than a small quantity of sand from entering the trap 9. When the sand has filled up the trap 9 to approximately the lower end of the pipe 39 the sand will cease to flow. However, when the exhaust is turned on to the pipe 8 the same will pass through the well 9 and strike the sand therein whereby said sand is distributed in a loose state to the pipes 34 and 35 and from thence to the nozzles 36 and 37. New sand is being continually supplied from pipe 39 as long as the exhaust is passing through the trap but as soon as the exhaust is turned off the trap fills partially as above described and then the sand ceases to flow. Any suitable tank or-reservoir may be provided for supplying the pipe 39 with sand, as for instance, the tanlr 48 shown in 1, said tanlr being suy ported in any suitable way, as for instance,

by pipe 39, though the pipe could be sup- I ported by the body of the vehicle and a role scoping pipe fitted within the pipe 39.

"What we claim is:

l. A sanding device for vehicles, comprising a plurality of sand distributing pipes, a trap connected with said pipes, a sand-supply pipe extending into said trap and. projcclg to near the bottom thereof, means for cca iping said supply pipe in any adjusted position, tubular members for connecting said trap with'the exhaust pipe of the engine of said vehicle, a valve arranged in said tubular members, and means for connecting said valve with the brake pedal of the vehicle whereby when the brake pedal is operated the valve will be opened for turning on the exhaust so that the same will blow the sand from the trap into said distributing pipes.

2. A. sanding device for motor vehicles,

comprising sand distributing members for ing said valves acting as operating means,

said connecting means holding the valves so that one is open while the other is closed, and means for connecting the operating means with the brake pedal of the vehicle whereby when the brake pedal is operated for applying the brakes said operating means will shift the position of said valves so that the valve to the muiiler will be shut 0E and the valve to the trap will be opened, thus allowing the exhaust to pass through the trap and force the sand therefrom to said distributing members. i

3. A sanding device for rnotor vehicles comprising a plurality of distributing pipes,

means for supplying a predetermined quan tity of sand adjacent said distributing pipes, and means for switching on the exhaust from the engine of the vehicle so that the ex-v haust will blow said predetermined quantity of sand through the distributing pipes,
